Thanks for the update.
Please note that this is not a standard deployment we recommend because it requires certain modifications that we do not handle. Are you using the vanderby/SonarQube-AzureAppService? You should check if you are running into any issues by checking the $SQ_HOME/logs folder.
Yes, a simple check with curl should give you truth about the SonarQube server, so you have a few tests to try at least:
- Curl from the Microsoft-hosted agent (add a script task)
- Curl from within the Azure App Service
- Curl from a remote server
